Aerospace - Design Elements

The vector stencils library "Carbohydrate metabolism" contains 25 icons of metabolite symbols.
Use these shapes for drawing carbohydrate metabolism schematics, biochemical diagrams and metabolic pathways maps.
"Carbohydrates are a superior short-term fuel for organisms because they are simpler to metabolize than fats or those amino acids (components of proteins) that can be used for fuel. In animals, the most important carbohydrate is glucose. The concentration of glucose in the blood is used as the main control for the central metabolic hormone, insulin. Starch, and cellulose in a few organisms (e.g., some animals ... and ... microorganisms), both being glucose polymers, are disassembled during digestion and absorbed as glucose. Some simple carbohydrates have their own enzymatic oxidation pathways, as do only a few of the more complex carbohydrates. The disaccharide lactose, for instance, requires the enzyme lactase to be broken into its monosaccharides components; many animals lack this enzyme in adulthood." [Carbohydrate metabolism. Wikipedia]
The shapes example "Design elements - Carbohydrate metabolism" is included in the Biology solution from the Science and Education area of ConceptDraw Solution Park.

The vector stencils library "Roofs" contains 21 roof clipart images.
Use it to create your landscape design and garden plans.
"A roof of a building envelope, both the covering on the uppermost part of a building or shelter which provides protection from animals and weather, notably rain, but also heat, wind and sunlight; and the framing or structure which supports the covering. ...
In most countries a roof protects primarily against rain. A verandah may be roofed with material that protects against sunlight but admits the other elements. The roof of a garden conservatory, protects plants from cold, wind and rain but admits light.
A roof may also provide additional living space, for example a roof garden." [Roof. Wikipedia]
The clip art example "Design elements - Roofs" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Landscape & Garden solution from the Building Plans area of ConceptDraw Solution Park.
