Introduction - NCP Flashcards
It is the principal form in which carbohydrate is used by the body
Glucose
abundant in fruits, sweet corn, and corn syrup
Glucose
Moderately sweet sugar found naturally preformed in few foods but mainly created in body from starch digestion
Glucose
The sweetest of the simple sugars
Fructose
found in honey, most fruits, and some vegetables
Fructose
this monosaccharide is not found in foods but is produced from lactose (milk sugar) by digestion and is converted into glucose in the body
Galactose
this disaccharide takes a form of ordinary table sugar-granulated
Sucrose
this disaccharide is composed of glucose and fructose
sucrose
found in milk and milk products except cheese
Lactose
This disaccharide is converted into glucose and galactose in digestion and is less soluble and less sweet than sucrose
Lactose
This Disaccharide remain in the intestine longer than other sugars and encourages the growth of certain useful bacteria
Lactose
This disaccharide is not found in free foods but i produced by hydrolysis of starch and is converted into glucose in digestion
Maltose
This disaccharide can be found in certain infant formulas, beer, and malt beverage products
maltose
This disaccharide is less sweet compared to glucose and sucrose
Maltose
How many sugar units are oligosaccharides composed of?
3-10 units of sugar
The most significant polysaccharide in human nutrition
Starch
Is the major food sources include cereal grains, potatoes and other root vegetables, and legumes. And it is more converted entirely into glucose upon digestion
Starch
sugar that are not found free in foods but instead are formed as intermediate products in the breakdown of starch
Dextrins
What are the hormones that increase blood sugar level?
- Glucagon
- Growth Hormone
- Steroid Hormone
- ACTH (Adrenocorticotropic Hormone)
- T4
Are formed from glucose and stored in liver and muscle tissues
Glycogen
Are non-digestible, colloidal polysaccharides having a gel quality and have sources that include mostly fruits and are often used as base for jellies
Pectins
Polysaccharide used to treat diarrhea, and give its whys
pectin,
as they absorb toxins and bacteria in the intestine. They bind cholesterol reducing the amount the blood can absorb
what are the two classification of cellulose, and give the difference
Soluble
- found sa mga fruits and legumes, barleys, and oats -
- delays gastrointestinal transit and glucose absorption
- lowers blood cholesterol.
Insoluble
- found in wheat bran, corn brans, whole grain bead, cereals, and vegetables
- accelerate gastrointestinal transit, increase fecal
weight, slow down starch hydrolysis
- delay glucose absorption
Polysaccharide that has no specific enzyme is present and provides important bulk in the diet which helps move digestive food mass along and stimulates peristalsis
Cellulose
the measurement of Normoglycemia
90 -120 mg/100ml of blood
only hormone decreasing blood sugar level
Insulin
This type of lipids are compounds of fatty acids, PHOSPHORIC ACIDS, and nitrogenous bases which also serves as EMULSIFIERS to keep the fat dispersed in the body fluid
Phospholipids
the most widely distributed phospholipid which traces are placed in liver and egg yolk and in raw vegetable oils such as corn oil. Carries fat & cholesterol away from plaque deposits in the arteries
Lecithin
type of phospholipid that are needed to form thromboplastin for the blood-clotting process
Cephalin
type of phospholipid that are found in the brain and other nerve tissues as components of myelin sheath
Sphingomyelin
Give the 3 types of common lipids
- Phospholipids
- Glycolipids
- Lipoprotiens
compounds of fatty acids combined with CARBOHYDRATES and nitrogenous bases
Glycolipids
type of glycolipid that are components of nerve tissue and certain cell membranes where they play a vital role in fat transport
Cerebrosides
type of glycolipid that are made up of certain glucose, galactose, and a complex compound containing an amino sugar
Gangliosides
what are the two types of glycolipids?
Cerebrosides and Gangliosides
are lipids combined with proteins
Lipoprotein
type of lipid formed primarily in the liver and are found in cell and organelle membranes, mitochondria, and lysosomes
Lipoprotein
what are the four forms of Lipoproteins>
CHYLOMICRONS
VLDLs
LDLs
HDLs
a type of lipoprotein that leave the liver cells full of fats & lipid components to transfer newly made triglycerides to the cells
VLDL
reduced as fats & lipids are released on their journey through the body. They carry cholesterol throughout the body to tissue cells for various function
LDLs
are formed within cells to remove cholesterol from the cell, bringing it to the liver for disposal
HDL
Health guidelines recommend a dietary cholesterol intake of ___ mg or less per day; If LDL cholesterol is elevated, dietary cholesterol intake should be less than ___ mg.
300mg, 200mg
Are simple derivatives from fat digestion or other more complex products.
Derived Lipids
They are fat substances produced from fats and fat compounds during digestive breakdown
Derived Lipids
Are key refined fuel forms of fat that the cell burns for energy. They are the basic structural units of fat and may be saturated or unsaturated in nature.
Fatty acid
Give the 3 sources of fatty acids
SATURATED FAT
MUFA - Mono Unsaturated fatty acid
PUFA - Poly Unsaturated fatty acid
type of fatty acid which no hydrogen can be added
saturated fats
what saturation of fatty acid remains solid at room temperature? Give an example
Fats high in saturated fatty acid / animal fats
[source of fatty acid] in which two of the carbon atoms are joined by a double bond
MUFA
[source of fatty acid] are those in which two or more double bonds are present. Linoleic acid is the most common example.
PUFA
is a water - soluble component of triglycerides and is inconvertible with carbohydrates
Glycerol
what percentage of glycerol comes out of the fat?
It comes out 10% of the fat.
are a class of fat-related substances that contain sterols
Steroids
________ is a main member of steroids
Cholesterol
are those which yield only amino acids upon hydrolysis.
simple proteins
are combination of simple proteins and nucleic acids.
Deoxyribonucleic nucleoproteins are necessary for the synthesis of proteins in the cytoplasm.
Nucleoproteins
[classification of protein] are compounds or metals attached to proteins found in ferritin, hemosiderin, and transferin.
