Answer:
Polypeptides are composed of amino acids, and we know amino acids are differently charged, have different R groups, and also have different isoelectric points. Depending on different isoelectric points and charged groups, the polypeptides can be separated and because a protein has its lowest solubility on its isoelectric point.
So in this question,
(a) (Lys-Ala)3 ; this is highly positively charged (polar) at pH 7 than (Gly)20 which is uncharged except for the amino and carboxyl terminal.
(b) (Glu)20 ; it is highly negatively charged at pH 7 whereas (Phe-Met)3 is much less polar and hence less soluble.
(c) (Asn-Ser-His)5 ; at pH 3, because in (Ala-Asp-Gly)5 the carboxylate groups of Asp residues are partially protonated and neutral, whereas in (Asn-Ser-His)5 , the imidazole groups of His residues are fully protonated and positively charged.
(d) (Asn-Ser-His)5; at pH 6.0; both polymers have polar Ser sidechains, but (Asn-Ser-His)5 also has the polar Asn side chains and partially protonated His side chains.
Explanation:
Fungi cell walls are made of chitin and other polysaccharides, not cellulose (Plants) or protein (Animals). Therefore your answer is-
"The cell walls of fungi are different than the cell walls of plants because they contain the hard material of chitin"
Answer:
True
Explanation:
Lipoprotein contain some amount of lipid, protein, phospholipids and cholesterol. It carries fat(lipid) molecules in the blood to different parts of the cells and tissues. Fats acts as insulators and protect vital organs.
High level of lipoprotein in the blood causes arteriosclerosis which is the blocking and clogging of the arteries with fats. These fats makes flow of blood difficult in the blood and it eventually causes heart related diseases and death.
