carbohydrates Flashcards
3 types of macronutrients?
carbohydrates
fat
protein
3 types of micronutrients?
vitamin
mineral
trace element
All macronutrients and micronutrients which 4 are organic? Which 2 are inorganic?
organic- include carbon atoms
carbohydrates/fat/protein/vitamin
inorganic- don’t contain carbon.
mineral/trace element/water
Two method to combine and splits?
condensation
combine together
hydrolysis
splits into small ones
carbohydrates 3 types? and example ?
momnosaccharide
glucose/fructose/galatose
disaccharides
surose/lactose/Maltose
polysaccharide
Brain only fuel used? for energy
glucose
most sweetest is?
fructose
lactose from?
Galatose combine to glucose
complex carbohydrate? x 2
how many sugar molecules chains composed?
oligosaccharides
chains composed 3 to 10 sugar molecules
polysaccharides
chains composed over 10 sugar molecules
oligosaccharides can break down by what?
which have a lot of oligosaccharides?
cannot break down by body just break down by intestinal bacteria Prebiotics
human breast milk contain a lot of oligosaccharide
polysaccharides 3 types?
starch
glycogen
fibre
starch 2 types?
is a polysaccharides
1)amylose 直鏈澱粉
2)amylopectin 支鏈澱粉
直鏈澱粉是一條直線,而支鏈澱粉則像有分岔一般,能增加與消化酵素接觸的表面積,所以消化速度快,但人體內分解澱粉的酵素主要是作用在直線處,因此分岔越多消化完整度越差。 所以一次大量攝食含較多支鏈澱粉的糯米製品容易伴隨消化不完全,腹脹、腹痛等腸胃不適情形。
where is glycogen from? break down to what?
storage in skeletal muscle and liver broken down to glucose
carbohydrate digestion? 3 steps?
use ? enzyme
digestion by ? where
starch throw amylase
maltose throw amylase
glucose throw Maltese
in small intestine
carbohydrate abortion in where?diffuse move to?
some monosaccharide from what to storage?
glucose/fructose/ galactose absorb by small intestine cells diffuse move to blood stream or to liver from glycogen to storage
