A) classify each of the following digestive products as hydrophilic or hydropphobic: monosacharides amino acids fatty acids minerlas vitamins B) desscribe the different paths of absorption and transport takenby hydrophilic vs hydrophobic nutrients as they move from intestianallumento the cells where theyr needed Solution A) Monosaccharides are hydrophilic or polar in nature as they are easily dissolved in water. Amino acids contain both hydrophilic and hydrophobic amino acids. Hydophilic amino acids include arginine, aspargine, aspartic acid, glutamic acid, histidine, lysine etc. Hydrophobic amino acids include alanine, glycine, phenylalanine, methionine, tryptophan and valine etc. The diet contains only essential amino acids that are not synthesized in our body. Fatty acids are hydrophobic in nature. Minerals are either hydrophilic or hydrophobic in nature. Vitamins include B complex, C vitamins that are hydrophilic and vitamins A, D, E and K are hydrophobic in nature. B) All hydrophilic molecules like monosaccharides, amino acids, minerals and vitamins are diffused across itestinal membranes. some substances like glucose require facilitated diffusion through Na+ / glucose cotransport. Some substances are absorbed through active transport means that require energy in the form of ATP. Fatty acids simply diffuse through the itestinal epithelium. Amino acids are mostly ansorbed through cotransport system. Minerals and vitamins are also absorbed by simple or facilitated diffusion..

nutrients as they move from intestianallumento the cells where theyr needed
Solution
A) Monosaccharides are hydrophilic or polar in nature as they are easily dissolved in water.
Amino acids contain both hydrophilic and hydrophobic amino acids. Hydophilic amino acids
include arginine, aspargine, aspartic acid, glutamic acid, histidine, lysine etc. Hydrophobic
amino acids include alanine, glycine, phenylalanine, methionine, tryptophan and valine etc. The
diet contains only essential amino acids that are not synthesized in our body. Fatty acids are
hydrophobic in nature. Minerals are either hydrophilic or hydrophobic in nature. Vitamins
include B complex, C vitamins that are hydrophilic and vitamins A, D, E and K are hydrophobic
in nature.
B)
All hydrophilic molecules like monosaccharides, amino acids, minerals and vitamins are diffused
across itestinal membranes. some substances like glucose require facilitated diffusion through
Na+ / glucose cotransport. Some substances are absorbed through active transport means that
require energy in the form of ATP. Fatty acids simply diffuse through the itestinal epithelium.
Amino acids are mostly ansorbed through cotransport system. Minerals and vitamins are also
absorbed by simple or facilitated diffusion.
