Question

Please help and I will rate a thumbs up! I really need help please.

1. What is the molecular diameter of the following molecules:

a) Starch

b) Albumin

c) Fructose

d) Lactose

e) Sucrose

f) Maltose

2. Also, what is the diameter of a hole in an artificial membrane composed of glycerol and cellulose?

Answer 1

1 e) The sucrose molecule is 1.06 nm in diameter, which is slightly larger than that of glucose (0.86 nm)

b) 3.8 nm in diameter and 15 nm long molecule

d ) The lactose, salt, and other minor soluble constituents have a diameter of 0.5 nm

f  )   Maltose is converted to two molecules of glucose by the enzyme maltase, which ... but is instead caused by the formation of particles <2 μm in diameter

a)   Rice starch granules are very small 6 μm diameter,

potato starch granules can exceed 100 μm.

The mean diameter of maize starch granules is 35 μm;

wheat starch has small (B) granules average 4 μm, while the large (A) granules average 14 μm.

c) 0.74nm

2)Typically the diameter of this hole is a few tens of micrometers up to hundreds of micrometers
