Macronutrients: Fats or Lipids Flashcards
what are the functions of fats
protection, insulation of heat, energy strorage
two types of fats
saturated and unsaturated
neutral fats
simple fats
chemical name foe basic fats
triglycerides
one type of fat is present
simple lipids
mixed of fats
compound lipids
three types of compound lipids
phospholipids, glycolipids, lipoproteins
compound of fatty acids, phosphoric acids, and nitrogenous bases
phospholipids
types of phospholipids
lecithins, cephalins, sphingomyelins
most widely distributed of the phospholipids. traces are places in liver and egg yolk and in raw vegetable oils such as corn oil. added to food products such as cheese, margarine, and confections to aid emulsifications
lecithins
needed to form thromboplastin for the blood-clotting process
cephalin
found in brain and other nerve tissues as components of myelin sheath
sphingomyelins
compounds of fatty acids combined with carbohydrates and nitrogenous bases
glycolipids
types of glycolipids
cerebrosides, gangliosides
components of nerve tissue and certain cell membranes where they play vital role in the transport.
cerebrosides
carbohydrate component is galactose
cerebrosides
made up of certain glucose, galactose and a complex compound containing an amino sugar
gangliosides
lipids combined with proteins
lipoproteins
what are the classification of fats
simple, compound, derived
simple derivatives from fat digestion or other more complex products
derived lipids
types of derived lipids
fatty acids, glycerol, steroids
key refined fuel forms of fat that the cell burns for energy. basic structural units of fat
fatty acids
souces of fatty acids
saturated fats, monounsaturated fatty acids, polyunsaturated fatty acids
no hydrogen can be added
saturated
example of saturated fats
palmitic and stearic acids
two of the carbon atoms are joined by a double bond
monosaturated fatty acids
most abundant monosaturated fatty acids
oleic acid
two or more double bonds are present
polyunsaturated fatty acids
most common of the polyunsaturated acids
linoleic acids
water-soluble component of triglycerides and is inconvertible with carbohydrate.
glycerol
class of fat-related substances that contain sterols
steroids
what is the main member of the steroids
cholesterol
Primary member of the omega-6 family
linoleic acid
Primary member of omega-3 family
linolenic acid
Only found in animal products
cholesterol
